We have demonstrated experimentally a highly efficient on-chip three-dimensional (3D) linearly tapered metal-insulator-metal (MIM) nanoplasmonic photon compressor (3D NPC) with a final aperture size of 14 × 80 nm2. An optimized and linearly tapered MIM gap plasmon waveguide could theoretically reduce the excessive losses that would occur during nanofocusing processes. In simulation study, this approach...
We propose an on-chip nano-horm-shaped metal-clad cavity. The proposed device is 0.8 µm in height-half the size of the previously reported devices— and achieves the quality factor of 1000 and effective volume of 0.31(λ/n)3.
We propose a new, simple way to engineer the radiation patterns of subwavelength-scale metallic semiconductor cavities for coupling light from a nanoscale metal cavity into integrated waveguides uni-/bi-directionally with efficiency up to ∼90%.
